WILLIAMS, OF BRANFORD, CONNECTICUT, ASSIGNOR TO. MAIQLEABLE IRON FITTINGS COMPANY, OF BRANFORD, CONNECTICUT, A CORPORATION OF CON- NECTICUT ELECTRIC RAILWAY EQUIPMENT Application filed March 8, 1929. Serial No. 345,540.

This invention relates to electric railway equipment, but more particularly has reference to the poles and cross beams which carry the conductor that supplies the electrical ourrent to the railroad train motors.

The object of the invention is to secure the cross-beams to the poles in such manner that the distance between the railway rails and such beams may be constant. In other words,

if, for any reason, the bed of the rails, and

consequently the rails themselves, should be raised or lowered, this invention: provides for this, in that the cross-beams are adjustably secured to the poles.

Since the presentinvention has nothing to any suitable manner.

In the accompanying drawings is shown a preferred embodiment of the invention, and in these drawings 7 Figure 1 is an elevation showing poles and cross beams broken away and in proper assembled condition- Figure 2 is a top plan view of the construction shown atFigure.1

Figure 3 is a section at the line 3-3 of Figure 2- 7 Figure 4 is a section at the line 44 of Figure 2- Figure 5 is a detail face view of the adjustable fixtures that are carried by the ends of the cross beams Figure 6 is a section at the line 66 of Figure 2 I V Figure 7 is a View of the inner face of one of the poles showing the manner of attaching the adjustable fixture thereto Figure 8'illustrates a modification showing the manner in which the fixtures are secured to the cross beam and poles when the latter are mounted in a position at right angles to that shown at Figure 1- v Figure 9 is a detail broken view illustrating a face view of the fixture when attached to the pole in the manner shown at Figure 8, and

' Figure 10 is a side elevation of the construction shown at Figure 9.

Similar numerals of reference denote like parts in the several figures of the drawing.

In carrying out this invention, both the poles and the cross beams are of the form known as H-beams, and in the construction shown at Figuresl to 7 inclusive, the continuous or fiat surfaces of opposite poles face each other, while the continuous or flat. surfaces of the cross beams constitute the upper and lower faces of said beams. In other words, in the construction'shown in Figures 1 to 7 inclusive the poles are so mounted that the cross bars of the H-structure are in planes that are at right angles to the railroad rails, the cross beam that is secured to opposite poles overhanging the rails in the usual'manner common to overhead electrification of a railroad.

Since this invention relates solely to the manner of securing the cross beams to the poles, so that said beams maybe at the proper height above the railroad rails, thefollowing description will be confined solely to anex-f planation of the manner in which said beams and poles are equipped for proper assembly and securement. 7 I r I In an overhead system the poles are mounted on each side of the railway, the poles on one side being opposite the poleson the other side, and cross beams connect each pair of opposed poles, but the drawings show only one pair of poles and a connecting cross beam, since further illustration is deemed unnecessary as it would'be a mere duplication, and the following description will of course, be likewise limited and will give a clear understanding of the invention.

Referring to Figures 1 to 7 inclusive, 1 are the poles and 2 the cross beam both of which are H-shaped in cross-section.

I The poles are E-lshaped and are preferably mounted opposite each other so that side surfaces 3 of the poles face inwardly towardeach other, as shown in the figures above named, and through the outer portions ofthese surfaces are series of uniformly spaced bolt holes 4:, and 5, are fixtures that are secured to these surfac by olts 6' extending through per-fora tions in these fixtures and through the holes at with nuts 7 driven on the ends of the bolts. In other Words, these fixtures are'bolted to thev poles, and the location of the fixtures, as far asheight is concerned, depends on the selection of the bolt holes 4 in the attachment of the fixtures. These fixtures are preferably r cessed, as at 8, so as to embrace the pole and thereby strengthen the connection between the fixtures and poles, and furthermore facilit'ating the sliding of the fixture to its desired location prior to the bolting.

Extending across the face of each of these fixtures are spaced'ribs 9 and intermediate these ribs are a series of teeth 10, as shown at Figures 2 and 7 and the bolts 6 extend through these ribs, the heads 11 of the bolts being countersunk Within the ribs so as to be flush with the faces thereof. 7

12 are plates that extend across'the ends of the cross beam 2, each plate. having rear extensions 13 that are positioned on opposite sidesof the Web 14 of said beam and are secured to said Web by bolts 15 and nuts .16, and it will therefore be 'clear'that these extensions are housed within the beams.

lVhen secured to the beam 2 as above set forth, the 'plateslQ are alongside each other in the same vertical plane, and each plate has recess 17 and a series of teeth 18, the space between'th'ese recesses being the same as the space between the ribs 9, and these plates 12 and their extensions 13 will hereinafter be referred to as a unit and will be styled the cross-beam fixture. V

In securing the cross-beam to the poles, the fixtures of the cross beams are assembled with the fixtures of the poles with the ribs 9 and the teeth 10 of the pole fixtures, and the rece%es 17 and teeth l8'of the cross-beam fixtures respectively.interengaged, and bolts 19 extend through elongated slots 20, 21, the outer edges of the pole and cross-beam fixtures respectively, and nuts 22 driven on the ends of the bolts. V

In the installation ofthe "system heretofore described, care must be taken to locate the cross-beams atjthe proper distance above the oad-he'd, and therefore the pole fixtures are bolted through selective holes 4, which may Or ma not be quite satisractory,a11d in the event that a slight elevation or lowering of the cross beams is desired, this may i-eadilybe effected by the interengagin-g of the teeth 10 and 18 higher up oriower down With respect to the poles, this being madep'ossible owing to the elongated slots QO and 21 through which the securing bolts 19 extend, it being, of course, understo'o'dthat this is done prior te the tight eni i'ig orthe boit s; Another advantage ef the iii e engaging teeth is that they sustain the t-of the cross-flieamto a great degree and s eyrelievethe bolts 19. I

It will further ppearthat fixturesyin terenga'ging' as they do-in their 'llbillltl recess formations, and positioned as they are with respect to the poles and cross-beam, are admirably adapted to resist strains in all directions, and to relieve the bolts.

In the adaptation of the invention as heretofore described, the poles are so mounted that their fixtures-are secured to the inwardly facing side surfaces of the poles, but the invention is utilized equally as Well, When the poles are mounted at rightangles to this'posi lion, that is to'say, with the web -portions 23 facing inwardlytoward each other:

Referringto Figures 8,9, and 10, a pole fixture 24 is shown which spans the space between the facesof the pole, is recessed at 25 to embrace said sides, and has lugs 26 that extend in contact With the inner surfaces of said sides and are secured thereto by bolts 27 passed through selective perforat ons 28 n the edge portions of said sides and nuts driven on said bolts.

In all other respects these fixtures are identical as to structure and function with the fixtures 5 heretofore described.

Having thus described my invention What I Y claim as new and desire to secure by'Let-ters Patent is 1. A support for electric railway equip 'ment, comprising opposite poles having fixtures adjustably secured thereto, cross-beams having fixtures secured across their ends,

both of said fixtures formed with parts adapt-- ed to interenga-ge at differentelevations, and

means for adjustably securing these fixtures together.

2. A support for electric railway; equipment,"compr1s1ng steel poles having adyu-su' ably secured thereto fixtures with a series of teeth extending from their faces, steel :crossthe fixtures may be adjustably secured to each other.

In testimony whereof I afiix my signature hereto. 1:
